Question

Pharmacist Doofenschmirtz must prepare a medicineinto 0.12 gram capsules. If he has 25.26 grams of themedicine, how many capsules can he make?

Answer 1

Solution:

Given:

$1\text{ capsule}=0.12gram$

The number of capsules he can make from 25.26 grams of medicine will be;

$\begin{gathered} 1\text{ }capsule=0.12gram \\ x=25.26grams \\ \\ Cross\text{ multiplying;} \\ 0.12\times x=1\times25.26 \\ 0.12x=25.26 \\ Divide\text{ both sides by 0.12,} \\ x=\frac{25.26}{0.12} \\ x=210.5\text{ capsules} \end{gathered}$

By long division,

$\begin{gathered} \frac{25.26}{0.12} \\ Multiplying\text{ both the numerator and denominator by 100 to remove the decimal,} \\ \frac{25.26\times100}{0.12\times100}=\frac{2526}{12} \end{gathered}$

Since he wants to make a whole complete capsule, then from 25.26 grams, he can make just 210 full capsules.
